INTRODUCTION
Pulmonary sequestration (PS) is a rare congenital lung malformation. The classical treatment of the disease has been conventional surgery with resection of abnormal parenchyma. Recently, the endovascular embolization has been proposed for the treatment of this disease. Here we present 2 cases of PS successfully treated with thoracic endograft.
PATIENT CONCERNS
Two patients with abnormal consolidation in the left lower lobe were admitted in our hospital.
DIAGNOSIS
Chest computed tomography angiography (CTA) showed abnormal consolidation in the left lower lobe, which received systemic blood supply from the descending aorta in both patients. So the diagnosis of PS was confirmed.
INTERVENTIONS
Endovascular treatment with thoracic endograft was successfully performed.
OUTCOMES
The patients recovered well and were completely free of symptoms. And the CTA follow-up showed the abnormal pulmonary parenchyma shrunk significantly.
CONCLUSIONS
Endovascular treatment with thoracic endograft is a promising treatment option for PS.
引言
肺隔离症（PS）是一种罕见的先天性肺畸形。该疾病的经典治疗方法是通过传统手术切除异常实质组织。最近，有人提出采用血管内栓塞术治疗这种疾病。在此，我们报告2例经胸内支架成功治疗的肺隔离症病例。
患者情况
两名左肺下叶出现异常实变的患者入住我院。
诊断
胸部计算机断层扫描血管造影（CTA）显示左肺下叶异常实变，两名患者的病变均接受来自降主动脉的体循环供血。因此，肺隔离症的诊断得以确诊。
干预措施
成功实施了经胸内支架的血管内治疗。
结果
患者恢复良好，完全无症状。CTA随访显示异常肺实质明显缩小。
结论
经胸内支架的血管内治疗是一种有前景的肺隔离症治疗选择。
